title: [Determination of thickness of concentration boundary layers for ternary electrolyte solutions and polymeric membrane].
abstract: The method to determine of the concentration boundary layers thicknesses (delta) in a single-membrane system containing electrolytic ternary solutions was devised using the Kedem-Katchalsky formalism. A basis of this methods is a square equation, contains membrane transport (Lp, sigma, omega) and solution (D, C, gamma) parameters and volume flux (Jv). Calculated values delta for aqueous potassium chloride and ammonia solutions are nonlinearly dependent on the concentrations of investigated solutions. These nonlinearities are the effect of a competition between spontaneously occurring diffusion and natural convection.
